6.5 MECHANISM AND RESOURCE SPECIFICATION

1. MECHANISM

Mechanism used is 'Compound gear train mechanism'.

2. RESOURCE SPECIFICATION

Motor Sizing

1)Volume of Shaft(Long) =27227.136 mm3

2)Volume of Gear(3.5 cm)=7969.484 mm3

3)Volume of Gear(4 cm)=10709.274 mm3

4)Volume of Gear(4.5 cm)=13841.837 mm3

*Total Volume=75686.699 mm3 =75.6866 cm3

*Mass=Density * Volume =Density of metal * Volume = 7.854 * 75.6866 = 594.4425 g/cm3

*Torque= Mass * pi * 0.6 * 1.5 = 594.4425 * 3.142 * 0.6 * 1.5 = 1680.9645 g/cm3 = 1.680 kg/cm3

= The Torque is 1.680 kg/cm3, so we use 60 RPM DC Motor.

Battery Sizing

sl.no	Components	Quantities	Operating Voltage	Operating current of each component	Total current
1	DC Geared Motor	1	12V	300mA	300*1=300mA
2	Arduino Mega 2560	1	5V	100mA	100*1=100mA
3	Dual-Channel Relay Module	1	5V	70mA	70*1=70mA

12V	5V
300mA=0.3A	170mA=0.17mA

We know that the factor of safety is 1.2

12V	5V
0.3*1.2=0.36A	0.17*1.2=0.204A

We use 12V and 0.5 A battery.
